Get one if you want, Life’s too short
I say get a winch if you want, but agree that you should at least learn how to use it.
Now, I have a response, I’m sure will be unpopular with a lot of you, but you don’t need the TRD Off-Road or TRD Pro to go off-roading. I’ve had several Jeep CJs, a Grand Cherokee and I’m on my second 4Runner (and that doesn’t include the 4x4 trucks I’ve owned), and with the SR5, I’ve gone nearly every place I’ve followed or led people with the TRD packages. Having KDSS is for people who need the aids. There’s nothing wrong with that, but some of us have been off roading long before any of these electronic nannies ever came out. As for rear lockers, the SR5 has A-TRAC in low range that’ll do just about everything you’ll ever need it to do. Granted, you’re going to need experience and proper tires, and possibly a lift kit, but unless you are doing serious rock crawling, requiring specialized equipment (and I’m talking competitions or rock faces) a properly equipped SR5 will go just about anywhere.
That being said, there’s nothing wrong with buying the TRD packages if that’s what you want. I’m an older person who prefers to do without the electronic gadgets as much as possible and would rather spend the extra money modifying my rig to my personal needs and desires.
